An inertial mass (2) is supported by a support frame (1) via spring means (3) to form a mass-spring system (2,3) having a resonance frequency (fn). A controller (6) is configured to control a force actuator (4) to adapt the driving force (Fd) as a function of measured vibra- tions (V1,V2). The controller (6) comprises a filter (H) determin- ing a magnitude (M) of the driving force (Fd) as a function of fre- quency (f) for the measured vibrations (V1,V2) in the structure (11). The filter (H) is configured to provide an anti-resonance dip in the magnitude (M) of the driving force (Fd) at the resonance frequency (fn) of the mass-spring system (2,3) to suppress reson- ant behaviour of the mass-spring system (2,3) itself.
